Well, I love SciFi and I am a sucker for well written time loops where a protagonist has to find a way out.
However, you provide so little info that it's virtually impossible to say anything about your idea. The super basic premise... mysterious car accident, weird things happen, you meet even weirder characters who speak some ominous lines of dialogue that hint at a time loop is certainly interesting enough. And I would certainly want to know more, i.e. check it out.
But we need to know more about the actual characters, what will the actual story be?
Also, since time loops are one of the more popular ideas in SciFi I recommend you try to spice it up a bit, i.e. try to find a new angle or at least an angle that has not been done to death.
I don't know how well versed you are with time loops in SciFi, if you have watched many of the numerous movies / tv shows that use this plot device or read books.
But it never hurts to immerse yourself into as much source material as possible for good ideas.
I would recommend you check out some of the lesser known works so whatever it is you want to write will not be just a mash-up of things fans of the genre have seen or read multiple times, i.e. don't make it Groundhog Day 2.0 or something like Edge of Tomorrow (the Tom Cruise movie) or Dr Strange (the first movie) or any of the things you can see in Star Trek. Of course the story will never be truly original, basically everything about this theme has already been written or filmed.
I recommend you check out the following:
12:01, you can find the movie for free on YouTube even, it's basically a SciFi version of Groundhog Day (the movie was made before Groundhog Day though), it also has a romantic angle (the hero tries to save his secret crush from certain death, and he's the only one who can remember the loops)

Retroactive - little known 1997 movie with James Belushi, also available for free on YouTube, here the heroine is the only one who can remember the loops (she's sent back in time numerous times)

Frequently Asked Questions About Time Travel - this is more of a comedy, but still pretty clever, it's a bit like Bill & Ted (a group of guys come up with a world changing idea in a pub), but it's not as goofy and dumb, also has some romance
Steins;Gate - pretty well known anime about time travel / time loops / alternate universes, but maybe worth checking out if you have never seen it, has some pretty good ideas and it also includes altering/erasing/changing memories of characters and only one person can always remember everything (and time is also frozen at various times).
A time loop concept I also liked was used in Blake Crouch's "Recursion" novel (the guy who wrote Wayward Pines, also a tv show), where your consciousness is sent through time into a previous version of yourself, here the b

asic premise is that someone wants to prevent the suicide of his daughter... then he's offered the deal of a lifetime by some shady organization that has apparently found a way to send people back in time, which works, daughter is saved, but then things gradually escalate to complete and total world ending apocalypse, which has to be prevented, so the heroes go back in time again and again and again (book has a happy ending). Makes clever use of time loops and erasing and sudden re-emergence of memories about former timelines.
Another book (that is not super well known) is "Paradox Bound" by Peter Clines, not so much time loop than time travel (it kind of has loops though), but maybe worth checking out, also has a romance angle.
